Well if you get lucky and it freezes up soon for you they will be locked under the ice typically for most of winter. You can trap them later after deer season with less worry about the intrusions. They are cutting the most trees right now as they are looking to buidl a food cache to get them through winter. They feed on those cut limbs under the ice.Was just about to inquire about beavers and this thread popped up. Had seen no sign of them until a few weeks ago on a rare trip into my sanctuary where I saw a pile of mature aspen laying down.. hate to put a ton of intrusion on the area to kill the bastards. How much time does a guy need to spend on ridding the place of them?
